Fix “Parameter Missing or Invalid” errors

Hi there,

Having an issue which I presume to be a result of using radio buttons for product variants (G:Variant app), but there is no button checked by default.

I checked the code and it appears to be correct, so I’m not sure why this error is appearing? Any help to ensure the first variant is auto-selected would be hugely appreciated.

{% form ‘product’, product, class: productClasses %}

Liquid code is only part of what could be at play here. JavaScript would also have some impact, and could be changing the selection on load.

Are you able to share a link to the product that shows this issue? Being able to see it will be a much better view of the problem.

Hi Jason,

Thank you so much for your response. It is happening with all products that
have variables. The shop is boleroeyewear.ca if that helps.
